Abstract

A method of providing a desired water level in a laundry machine by energising the motor of the machine intermittently to produce changes in velocity of the spin tub, agitator and a load of clothes in the spin tub. The changes in velocity are measured and from the measurements the mass of the load of clothes is determined. A desired volume of water necessary for an optimum wash of the load of clothes is then determined and this volume of water is admitted to the washing container of the laundry machine.
